and in ethanol for 10 min by ultrasonic cleaning. Al films were prepared by DC magnetron sputtering using aluminum target with purity of 99.99% in an ultra-high vacuum system with ion gun. Ar ion cleaning before... was carried out to study their anticorrosion performances. The results show that the surface hardness of AZ31B magnesium alloy with aluminum film is 1.38-2.01 GPa, higher than that of the magnesium alloy......
Dissimilar friction stir welding between 5052 aluminum alloy and AZ31 magnesium alloy YAN Yong(鄢 勇), ZHANG Da-tong(张大童), QIU Cheng(邱 诚), ZHANG Wen(张 文) School of Mechanical and Automotive... aluminum alloy; AZ31 magnesium alloy; microstructure evolution; mechanical property 1 Introduction Aluminum alloys are widely used in automotive, aerospace and ship industries due to the combination......
on the investigation of stress relaxation of AA5182 during hot deformation, a new method to model the recovery process in the aluminum alloy has been provided by BANGE [8]. Due to the requirement of high quality, AA5182 aluminum sheets are usually produced by high-speed hot tandem rolling. Meanwhile, as aluminum alloy 5182 belongs to high strength aluminum alloy compared to 1××× and 3××× aluminum alloys, it has......
